ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 Main servo drive unit variants
Main servo drive units for the ABB robot controller drive system, identified by the complete ABB model and ordering record.
01
Product Summary
ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 identifies two ABB main servo drive unit records. Their ordering numbers distinguish the connected drive-channel arrangement required by the installed controller configuration.
In the robot controller, ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 links controller commands with the motor power stages and reports drive state back to the controller. Selection therefore follows the installed axis configuration and the complete nameplate record.
Service on ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 controls mains and DC-link energy, records all drive connectors and preserves the cabinet cooling path. After installation, drive readiness and the affected axes are verified individually before the robot is returned to coordinated motion.

System Integration
Each DSQC617 ordering record occupies a defined place between controller drive commands, motor connections and diagnostic feedback.
Axis power path
The exact ordering number identifies the motor-channel arrangement that must match the installed robot.
Diagnostic return
Ready and fault conditions return to controller diagnostics before coordinated motion is allowed.
04
Installation Highlights
Controlled replacement sequence
Replacement preserves electrical isolation, cooling and the original channel-to-connector mapping.
Discharge stored energy
Isolate mains and verify the DC link before removing any drive connection.
Reproduce the cabinet installation
Transfer connector labels, seating and airflow clearances to the replacement unit.
Test in stages
Confirm drive readiness, test each affected axis at controlled speed and then verify coordinated robot motion.

Questions & Answers
What distinguishes ABB DSQC617 3HAC14546-4 from DSQC617 3HAC14546-6?
The ordering records represent different installed drive-channel arrangements.
Why must the full model be used for ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6?
DSQC617 alone does not identify the exact ordering record.
Which energy must be controlled before servicing ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6?
Isolate mains and verify that the DC link has discharged.
Can ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 be enabled immediately after connection?
First confirm connector mapping, cooling, drive configuration and a fault-free readiness state.
How should ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 be tested?
Test affected axes individually at controlled speed before coordinated motion.
What should be retained with an ABB DSQC617 3HAC14546-4 / DSQC617 3HAC14546-6 service record?
Keep nameplate photographs, complete ordering number, connector map, fault log and commissioning results.
